Resource depletion: the exhaustion of raw materials within a region
Electric car batteries: nickel--> extracted from the earth by mining harmful for the environment Magnesium--> extracted by electrolysis; magnesium is also very toxic when being extracted cobalt silicon
Mobile phone batteries: nickel--> when extracting nickel it can be directly harmful to the environment due to acid leaching
'a material used in the manufacture of touchscreens – are likely to run out by 2020.'
mining of Rare earth metals: needed for every type of technology to be built -china -Kazakhstan - California
--> China owns 97% of the mines so they are in control on who get rare earth metals --> California can over take chinas market with the amount of rare earths they have however there are too many health risks involved for them to re-open the mine
